Title: Light emitting diode array device
Inventor: TAKANISHI HIROYOSHI
IPC: H04N1/04
Filed: 1990-03-30
Abstract: PURPOSE:To restrain heat released from a light emitting diode from being conducted to a rod lens so as to prevent the rod lens from deforming and deteriorating in light distribution characteristic and to protect the light emitting diode, the lens, and others against damage. CONSTITUTION:LED pellets 2 disposed on a wiring board 1 are selectively turned ON through a wiring provided to the board 1. Light emitted from the pellets 2 is condensed through a rod lens 3 and projected. At this point, heat released from the pellets 2 and conducted to the board 1 is transferred to the lens 3 only through a protrusion 30. That is, as a cavity 30 and a gap 34 are provided between the lens 3 and the board 1, a contact area between the board 1 and the lens 3 is very small, whereby heat released from the pellets 2 is hardly conducted to the lens 3 even though the lens 3 is directly fixed to the board 1. Furthermore, air is made to flow into the vicinity of the pellet 2 from outside by convection through the intermediary of the gap 4 which communicates with the cavity 33, so that heat released from the pellet 2 is effectively dissipated and the pellet 2 is prevented from deteriorating in service life and characteristics due to an thermal effect and improved in light power maintaining factor. Heat itself conducted from the pellet 2 to the board 1 is made to decrease.

Filed: 1989-03-31
Abstract: PURPOSE:To miniaturize an optical information processor and also to improve the focus detecting sensitivity by using a convex lens having a large refractive index to form a tracking detecting optical system. CONSTITUTION:The light beam undergone a focusing function of an objective lens 8 is reflected by a beam splitter 6 and made incident on a convex lens 12 attached to the light incident surface of a half prism 14.

Abstract: PURPOSE:To erase undesired data and to avoid erasion of those data to be preserved permanently by storing data in the 1st erasion-enable memory means or the 2nd erasion-unable memory means in response to the specific data added to the memory data supplied from outside. CONSTITUTION:An address storing data to be erased and the specific conditions for erasion are supplied to a CPU 3 from a CPU 11 of an IC card handling machine 10. The CPU 3 decides whether the data can be preserved permanently or not by a fact whether a flag is set up or not in an area (e) included in the property information (b) added to the data stored in the address supplied. If it is decided that the data cannot be preserved permanently, the CPU 3 decides whether the coincidence is obtained between the specific conditions for erasion supplied and the specific conditions for erasion of an area (f) in the information (b) added to the memory data. When the coincidence is obtained, the memory data is erased. While the property discordance signal is supplied to the CPU 11 in case data can be preserved permanently. Thus it is possible to erase the undesired data and avoid erasion of the data to be preserved permanently.
