Abstract
Abstract A display device for displaying the scanning speed of a hand scanner is described. An encoder 28 detects the scanning speed of the hand scanner. A microprocessor 26, 30 produces a series of display driving signals, in each case when the scanning speed exceeds a respective one of an increasing sequence of preset scanning speeds. A series of display elements 1-7 responsive to respective display driving signals indicate whether the scanning speed exceeds the respective preset scanning speeds.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
61 words
A display device for displaying the scanning speed of
a hand scanner comprising: means for detecting the scanning speed of the hand
scanner; control means for producing a display driving signal
when the scanning speed exceeds a preset scanning speed;
and a display element responsive to the display driving
signal for indicating whether the scanning speed exceeds
the preset scanning speed.
Claim 2
Dependent Claim
66 words
A display device according to claim 1 in which the
control means is adapted to produce a series of display
driving signals, in each case when the scanning speed
exceeds a respective one of an increasing sequence of
preset scanning speeds and comprising a series of display
elements responsive to respective display driving signals
for indicating whether the scanning speed exceeds the
respective preset scanning speed.
Claim 3
Dependent Claim
26 words
A display device according to claim 2 in which the
sequence of display elements is arranged in the same order
as their respective preset scanning speeds.
Claim 4
Dependent Claim
33 words
A display device according to claim 2 or claim 3 in
which the control unit further comprises a memory for
storing data relating to a range of scanning speeds divided
into multiple sub-ranges.
Claim 5
Dependent Claim
18 words
A display device according to claim 4 in which the
sub-ranges are bounded by the preset scanning speeds.
Claim 6
Dependent Claim
36 words
A display device according to any one of claims 2-5 in
which only one display driving signal is produced
corresponding to the highest of the preset scanning speeds
which is lower than the detected scanning speed.
Claim 7
Dependent Claim
31 words
A display device according to any one of claims 2-5 in
which all display driving signals corresponding to preset
scanning speeds which are lower than the detected scanning
speed are produced.
Claim 8
Dependent Claim
82 words
A display device according to any preceding claim in
which the means for detecting the scanning speed of the
hand scanner comprises: an encoder mounted for rotation with a moving roller
of the hand scanner and including a disc having a
circumferential array of slits; and a pulse waveform production unit including a light
receiving unit and a light emitting unit, for outputting a
pulse only when one of the slits passes between the light
receiving unit and the light emitting unit.
Claim 9
Independent Claim
33 words
A method of displaying the scanning speed of a hand
scanner comprising: detecting the scanning speed of the hand scanner; activating a display element when the scanning speed
exceeds a preset scanning speed.
Claim 10
Dependent Claim
32 words
A method according to claim 9 comprising: activating a series of display elements, in each case
when the scanning speed exceeds a respective one of an
increasing sequence of preset scanning speeds.
Claim 11
Dependent Claim
27 words
A hand scanner including a display device according to
any one of claims 1-8 or adapted to perform a method
according to claim 9 or claim 10.
Claim 12
Dependent Claim
25 words
A display device for displaying the scanning speed of
a hand scanner as described herein with reference to and as
illustrated in the accompanying drawings.
Claim 13
Independent Claim
24 words
A method of displaying the scanning speed of a hand
scanner as described herein with reference to and as
illustrated in the accompanying drawings.
