Filed: 1988-03-15
Abstract: PURPOSE:To prevent an optical carriage from being locked at its return with pressing rollers by arranging a lower roller so as to be pressed by a guide with the aid of an elastic shaft. CONSTITUTION:The title device is provided with a pair of pressure rollers 43 consisting of an upper roller and the lower roller supported by the elastic shaft. When a first optical carriage 38 is on its way scanning an original 27a, it is prevented from jumping by means of the pressure rollers 43 tightly holding a first guide rail 42 despite moment produced at the beginning of movement.

IPC: H01Q1/22
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent an antenna from being damaged by housing the antenna into a grip without increasing the size of the equipment main body. SOLUTION: This housing mechanism is provided with a grip 14 to be gripped by inserting a hand to a notched escape part 12 at the time of carrying the equipment main body 10 and a housing section 16 in which an antenna 18 is housed in the group. Since the antenna 18 housed in the housing section and the group 14 are not projecting from the equipment main body 10, the antenna 18 and the group 14 cause no hindrance to external appearance. Furthermore, in the case of carrying the equipment main body 10, the antenna 18 is not touched in mistake and no unexpected force such as loading a thing on the antenna 18 or the fallen off of the equipment main body 10 or the like is exerted to the antenna 18 when the antenna is not in use (housed) thereby preventing deformation or damage of the antenna 18. Since a notched space to house the antenna 18 in the equipment main body 10 is omitted, it is not required to increases the size of the equipment main body 10.

Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To appropriately transmit voice and the like to a base station from portable communications equipment by receiving a space wave signal radiated from the transmission part of portable communication equipment, generating a second guided radio signal from the received space wave signal and transmitting the second guided radio signal to a guide line. SOLUTION: A portable radio equipment 100 converts voice which is to be transmitted to an operation command 1 into a signal S3 having a frequency f3 and radiates it. One of space wave receivers 23a-23c receives the signal S3, converts it into a signal S2 and transmits it to a base station 2. Since the signal S3 is the signal of a UHF band, a transmission possible range becomes wider than that of the signal S2. The possessor of the portable radio equipment 100 can make a call with the operation command 1 even if he is apart from a guide line 3 even if he is in the transmission possible range of the signal S3. Even if the signal S3 is radiated from a transmission antenna 22, the signal S3 is transmitted farther than the signal S2.
