After serial signals output from a CCD sensor are amplified, a peak value of white levels corresponding to the space portions of bar codes is held by a peak hold circuit, and then the held peak value is converted into a digital value by an analog-to-digital conversion circuit. The value obtained by multiplying accumulation time data from the CCD sensor by the target value of the white level peak value is divided by the digital value. The next accumulation time of the CCD sensor is set on the basis of the result of this division. In this way, the sensitivity of the scanner is adjusted.

A code reading apparatus of a bar code reader which has detecting means for outputting a reading signal responsive to the code displayed on a medium, edge detecting means for detecting the edge of the reading signal, counting means for starting counting each edge detected by the edge detecting means. Discriminating means outputs a reset signal to decoding means when the counted value started for counting by the counting means is a product or more of the quotient produced by dividing the allowable maximum width of the code by the allowable minimum width and the counted value counted between the edges immediately before by the counting means, when the quotient produced by dividing the counted value started for counting by the counting means by the counted value counted between the edges immediately before is a quotient or more produced by dividing the allowable maximum width of the code by the allowable minimum width. Thus, the apparatus can discriminate the start even if the starting margin before the code of the bar code is short.

This invention relates to a photoelectric switch and a photoelectric detector for detecting the presence or absence of an object by using a light, and more particularly to prevention of mutual interference in the case of using a plurality of photoelectric switches. For example, an LED in a light emitting unit intermittently emits a sensing light at the timing of an output pulse from a pulse generator. The resultant pulse is divided in frequency by a frequency divider and then delayed by a one-shot circuit. At the timing of an output pulse from the one-shot circuit, another LED emits a transmission light to a photoelectric switch at next stage. Therefore, the transmission light is always delayed from the sensing light. The transmission light from the preceding photoelectric switch of the same construction is received by a photodiode, and an output pulse is outputted from a pulse generator in synchronism with a synch timing signal produced from the light receiving unit. Thus, the sensing lights from the respective photoelectric switches are emitted at the timings shifted from one another through delays effected by the one-shot circuits.

The accuracy of a measurement value obtained by a tire pressure detection device is lowered by a centrifugal force and an inertial force during travel. A pressure sensor (30) displaces a diaphragm (20) in its vertical direction (32) according to the pressure. The pressure sensor (30) is arranged in a tire (2) with the vertical direction (32) directed to a direction parallel to a rotation axis (34) instead of the tire circumferential direction or radial direction. The pressure sensor (30) is mounted onto a substrate with the vertical direction (32) of its diaphragm (20) directed in parallel to the substrate surface and the substrate is bonded to a tread portion of the tire (2) and a wheel rim portion while adjusting the vertical direction (32) of the diaphragm (20) with the direction of the rotation axis (34).
