摘要:
A thermal printer which is designed to reduce costs by reducing the number of parts, and which can easily drive a carriage using an inexpensive low-power drive motor by reducing a load acting on the part of the carriage which carries a thermal head. The carriage is provided so as to travel reciprocatively along a platen. A thermal head is directly attached to the opposite side of the carriage to the platen without any intervening member. A biasing member is disposed for urging the carriage toward the platen.

A tape transport for driving a continuous master tape and a copy tape through a tape contact printing station at a very high speed. The master tape has a prerecorded signal the reverse image of which is transferred onto the copy tape by the tape contact printing station. The tape transport enables the master and copy tapes to maintain contact and registration with the required degree of accuracy to produce an acceptable signal transfer which generates a high quality video signal for use in home video cassette recorders and viewing equipment.

There is provided a thermal conductivity sheet capable of lowering the thermal resistance value of the joint surface more than before in addition to easiness to use, and an electronic device to which the thermal conductivity sheet is applied. Load is applied to the thermal conductivity sheet having a prescribed thickness placed between CPU 10 that is the heat generation parts and the heat sink 11 that is the heat radiation parts. The thermal conductivity sheet has hardness wherein intervals between CPU 10 that is the heat generation parts and the heat sink 11 that is the heat radiation parts narrow more than the prescribed thickness by either of load within the range from 0.01 kgf/cm2 to 5.0 kgf/cm2 with tightening of screw.

摘要:
Electronic components differing in height (a CPU 2a, a capacitor 2b, and coil elements 2c) are mounted on a printed circuit board 1. A heat-absorbing member 3 is provided above the printed circuit board 1 in such a way that the member 3 contacts not only the top surface of the CPU 2a that is the shortest but the sides of the capacitor 2b and the coil elements 2c. To circulate a cooling medium, a flow path 4 is formed in the heat-absorbing member 3. Heat generated at the CPU2a is transmitted from its top surface to the cooling medium in the flow path 4 via the heat-absorbing member 3; heat generated at the capacitor 2b and the coil elements 2c is transmitted from their sides to the cooling medium in the flow path 4 via the heat-absorbing member 3.

A head up-down mechanism in a printer is to be provided wherein, by a simple construction, a carriage is returned up to a printing start position while a thermal head is spaced apart from a platen and at the same time there is performed a paper feed operation and which can thereby improve an effective printing speed. To this end the head up-down mechanism includes a head up-down lever with a thermal head mounted thereon at a position opposed to a platen, the head up-down lever being supported pivotably by a carriage which reciprocates along the platen between both side plates spaced a predetermined distance from each other, an urging member for urging the head up-down lever in a direction in which the thermal head comes into abutment against the platen, and a head up-down cam which is moved by abutment thereof against each of the side plates and which causes the head up-down lever to turn so that the thermal head comes into or out of contact with the platen.

摘要:
DIMMs to be cooled are mounted in DIMM areas of a printed circuit board of a system board. An air intake port that introduces cooling air is arranged on a side plate of the system board, whereas an air discharge port that discharges the cooling air is arranged on another side plate. The cooling air flows in a direction that is oblique with respect to the side plate. The air intake port is arranged at a position that is offset in the direction in which the cooling air is supplied. Accordingly, cooling is possible by efficiently bringing the cooling air into contact with the DIMMs.
