Title: Vehicular lamp device
Inventor: SAKAI TAKAKO
IPC: F21V31/03
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To make a breathing hole hard to see through an outer lens by forming, on the inside surface of the back wall part of a housing, multiple curved reflecting surfaces to reflect the light from a bulb in a diffused form interposing borderlines, and by forming the breathing hole on the borderline of the curved reflecting surfaces. SOLUTION: The light from a bulb is reflected forward in a diffused form by forming curved reflecting surfaces 8 on the inside surface of a back wall part 5 of a housing of a lamp device that is a turn signal lamp mounted to a front part of an automobile by means of aluminum deposition. The curved reflecting surfaces 8 are plurally formed interposing borderlines. The curved reflecting surfaces 8 each have a convex shape toward the inside of the housing. A breathing hole 9 is formed at a diagonally upward position of the bulb in the back wall part 5 of the housing. The breathing hole 9 is formed at a position in coincided with one of borderlines L of the curved reflecting surfaces 8. Thereby, the breathing hole 9 becomes less conspicuous than it is formed at a part other than the borderlines L.

Title: Bar code reader
Inventor: KITAMURA NOBUYUKI
IPC: G06K7/016
Filed: 1989-10-16
Abstract: PURPOSE:To make it possible to read out a bar code at the time of detecting an article and to prevent the article from being misdetected by arranging the detecting direction of an article detecting sensor obliquely downward so that the detecting area of the article detecting sensor is superposed to the readable area of a scanning reading part. CONSTITUTION:The detecting direction of the article detecting sensor 13 is arranged obliquely downward so that the detecting area SA of the sensor 13 is superposed to the readable area RA of the scanning reading part 20. Since the detecting direction of the sensor 13 is directed obliquely downward, an operator or the like does not directly enter into the detecting area SA even when the bar code reader is vertically arranged, so that the generation of misdetection due to operator's movement or the like can be prevented. Since the area SA is superposed to the area RA, the generation of a trouble such that a bar code can not be detected even if an article is detected can be prevented. Consequently, article detection in the vertical type device can be surely executed and its reading performance is also improved.
