A printer, including a first and a second feed mechanism supported by a carriage for feeding a print ribbon and an erase ribbon, respectively, at least one rotatable shaft supported by the reciprocating carriage rotatably in opposite directions, a one-way clutch for transmitting the shaft rotation in one of the opposite directions to the first feed mechanism, and inhibiting transmission of the rotation in the other direction, and a control mechanism for inhibiting transmission of the shaft rotation to the second feed mechanism when the printer is in a printing mode, and transmitting the shaft rotation to the second ribbon mechanism when the printer is in a correction mode, whereby the carriage reciprocation activates the first and second feed mechanisms. A converter may be provided for converting the shaft rotation into movements of a ribbon lift to shift the erase ribbon between an erasing and an inoperative position. The rotation control mechanism inhibits transmission of the shaft rotation to the converter while in the printing mode, but transmits the rotation to the converter while in the correction mode. Thus, the carriage reciprocation also cause the shifting movements of the erase ribbon.

In a printing device according to the present invention, a housing assembly comprises a pair of housings which are rockably supported, with their respective open end portions abutting against each other. A platen is disposed in an abutment region where the open end portions abut. A keyboard is provided on the one housing, while a printing element is disposed inside the other housing. When the printing device is in a nonusable position, the two housings extend along one plane, thus defining a flat, rectangular outline of the housing assembly. When the device is in a usable position, the housings are rocked relatively, thus defining a substantially L-shaped outline of the housing assembly. As the housings rock in this manner, the printing element is brought to a printing position, where the element faces the platen.

For a foodstuff of which the main component is protein and which is to be refrigerated or chilled for storage, it is desired to improve it so that it can be cooked easily in a short time and is superior in flavors, tastes and hygiene. Before refrigerating grilled chicken on a stick as the foodstuff to be cooked by heating, it is preheated by passing electricity to a temperature not less than the temperature at which protein is denatured and less than the cooking temperature until its protein is uniformly denatured to the inside thereof so that simply by preheating at least its outside to a temperature not less than the cooking temperature during cooking by heating, tastes in which the entire grilled chicken is heated to the inside are obtainable and it can be cooked easily with no variation in a short time with excellent flavors and tastes.

A contact type color image sensor reads out a document image at its actual size while moving along the length of the document. The photosensitive cell arrays, each having pixel electrodes which prescribe n photosensitive cells (where n is a positive integer), are aligned on the substrate. Filter films are positioned over the cell arrays. The radiated image light is converted into the three primary color components of red, green and blue, and R, G, B color signals necessary for color reproduction of the document image are obtained from the respective cell arrays. The n photosensitive cells are arranged at a predetermined pitch p along the main scanning direction X in each array, and the cell arrays are arranged at a sub-scanning direction pitch q which is larger than the pitch p by a factor of K (where k is larger than 1 and k.times.n is a natural number).

A power operated typewriter having an end of line locking mechanism comprises a clutch interposed between a drive motor and a printing mechanism, a control lever for engaging the printing clutch to print a character by the printing mechanism when a key lever is depressed, and lock means for locking the control lever so as to hold the printing clutch in its disengaged condition, which can prevent any printing operation even if the key lever is depressed after the right-hand margin position has been reached and is operative.

A system interruption apparatus alternately sends interruption signals INT1 and INT2 at first time intervals to a central processing unit executing an operation if interruption does not occur within a second time interval to thereby cause an interruption and suspend the operation of the central processing unit.
