摘要： PURPOSE:To provide an inexpensive image forming apparatus not requiring an elastomer such as a spring for imparting tension to an aperture electrode. CONSTITUTION:When a support member 61 is bonded to an aperture electrode body 1 by a thermosetting adhesive to be held to low temp. for the sake of curing, the support member 61 is more largely contracted by the difference of the coefficient of thermal expansion and, when the support member is heated to a room temp. after the adhesive is cured, the aperture electrode body 1 extends more largely this time and, therefore, tension remains in the aperture electrode body 1. As a result, the aperture electrode body 1 has no bending rigidity because it is composed of a polyimide film with a thickness of several ten mum but generates the force to strain by applying tension to the electrode body and the polyimide film is vibrated so as to follow a vibrator. Therefore, only the aperture vicinal part 64 receiving tension is vibrated to shake off the toner bonded to apertures 6.

摘要： PURPOSE:To recognize at once in whichever side a new essential picture is formed by providing constitution such that a marking means is actuated to perform marking on a reverse side of fed paper when a mode for marking on the reverse side is selected. CONSTITUTION:When a marking select key on a panel is pressed down further to press down a copy start key, a marking mode is obtained by the marking select key, and a data from a memory is output by a copy start command and to a laser beam oscillating source 17 through a buffer. In a marking device 200, in order to print a mark for showing a sheet in a reverse side, for instance, star mark and a character of reverse side, a thermal head 201 is successively drive heated, and the sheet is conveyed by rotating a thermal platen 203. In this way, ink of an ink ribon 202 is melted in the reverse side of the sheet to print the star mark and the character of reverse side on the reverse side of the sheet.

摘要： PURPOSE:To make the winding of a fan unnecessary and reduce the size as well as the weight of the fan by a method wherein the fan is provided with an annular supporting member, provided around the outer periphery of the fan to support the fan and rotated integrally with the fan, and an ultrasonic motor, welded to the supporting member by pressure and rotating the supporting member. CONSTITUTION:Ultrasonic oscillators 11 are embedded into the case 36 of the main body of a fan 31 and are welded by pressure to a circular ring 34 through retaining members 35 while blades 33 are supported from the circular ring 34 toward the central part of the fan and a hub 32 is fixed by supporting rods at the central part of the fan. The ultrasonic oscillators 11 form driving units 37a, 37b at both end units where the maximum oscillation can be obtained. According to this method, the winding of the fan may be made unnecessary and the size as well as the weight of the fan may be reduced.

摘要： PURPOSE:To lower the running cost of an ink ribbon by constituting the title printer so that the ink ribbon is relatively moved in the direction reverse to that during printing with respect to a thermal head after the finish of erasure operation for performing the release erasure of ink. CONSTITUTION:A heating means is driven while a thermal head 17 and an ink ribbon 14 are relatively moved in the first direction in such a state that the ink ribbon 14 is held between the thermal head 17 and printing paper 5 to heat the ink ribbon 14 and the ink already transferred to printing paper 15 by the sticking force of the ink is released and erased. After the finish of erasure operation, the ink ribbon 14 is relatively moved in the second direction reverse to the first direction with respect to the thermal head 17. Thereby, after the finish of erasure operation, the ink ribbon 14 used in erasure operation is unwound and again used in printing or erasure to make it possible to lower the running cost of the ink ribbon 14.

摘要： PURPOSE:To inform workers of a dead cell or battery and prevent a plant from being killed by discriminating a voltage of a power source part in supplying water and displaying an alarm without operating an air pump when judging the voltage to be a prescribed value or below. CONSTITUTION:Water in a water feed tank 3 storing the water is supplied with an air pump 15 for supplying the water to a flowerpot 5. In the process, when the time set with a time setting switch is attained, the voltage of a cell or battery 9 is judged to be a prescribed value or below. When the voltage of the cell or battery 9 is judged to be the prescribed value or below, an alarm is displayed without operating the air pump 15.

摘要： PURPOSE:To automatically supply water and prevent a plant from being killed by judging a voltage value of a power source part when the time set with a time setting means is attained, memorizing the judged result and supplying water if the voltage is the prescribed value or below when exchanging the power source part. CONSTITUTION:Water in a water feed tank 3 storing the water is supplied with an air pump 15 for supplying the water to a flowerpot 5. In the process, if the voltage of a cell or battery is judged to be a prescribed value or below when the time set with a time setting switch is attained, a flag is erected in a memory region. When the cell or battery is exchanged next time, water is supplied if the flag is erected.

摘要： PURPOSE:To obtain a clear image without shadow by providing a means for switching a light irradiating direction in a light source in the case that liquid crystal shutter bodies which can be opened and closed are respectively provided in plural light transmitting parts and the image is formed on a photosensitive body with light passing through the light transmitting part. CONSTITUTION:A light source unit can move along a guide 22 from a position A to a position B, and it can rotate centering around a rotary shaft 21 provided in parallel with the longitudinal direction of a light shielding part 26, then it can finally move a position C. In order to avoid double exposure, the light shielding part 26 of an LCD 7 is formed so that its width may be the same as that of an image forming part, and a distance between to light sources which respectively exist at the positions A and C is the same as a distance to the LCD 7 from the light source. Therefore, the shadow of the light shielding part which is exposed with the light in one direction is exposed with the light in the other direction by switching the position or the light irradiating direction of the light source for exposing the image. Thus, the clear image without the shadow is obtained.
