An infant carrier apparatus comprises a support frame, a handle pivotally coupled with the support frame, and a safety lock. The support frame can include first and second frame portions pivotally coupled each other, whereby the first frame portion can rotate relative to the second frame portion between collapsed and deployed states. The handle can rotate relative to the support frame between two positions of opposite inclinations. The safety lock is assembled between the handle and the first frame portion, and is triggered by a rotational movement of the handle to lock the first and second frame portion. The safety lock is unlocked to allow relative rotation between the first and second frame portion when the handle is in the first position. The safety lock rotationally locks the first and second frame portion when the handle is in the second position.

Operability of a heating cooker having a heating unit in a top plate is improved. After power-on, a light emission control unit causes the operation unit light-emitting element of an operable operation inhibition releasing key to be lit so that only the key is displayed and the other keys are less visible. Thus, the heating cooker is changed into a lock state. When the operation inhibition releasing key is operated in the lock state, at least one electrostatic touch key other than the operation inhibition releasing key is made operable and the operation unit light-emitting element is lit. Alternatively, in the above structure, the operation unit light-emitting element of the operable operation unit is lit in a first light-emission color, and the operation unit light-emitting elements of the inoperable operation units are lit in a second light-emission color different from the first light-emission color. Thus effective operation can be guided.

According to the present invention, an input buffer circuit comprises a first and a second buffer circuits operated at different first and second drive voltages and connected in turn, and an output potential control circuit is provided for carrying out a control so that, in spite of a voltage value of the first drive voltage, a threshold of an output potential of the first buffer circuit becomes a threshold of an input potential of the second buffer circuit. Further, the output potential control circuit is configured such that the first buffer circuit is constituted by a pair of complementary current mirror amplifiers, and comprises feedback control means for carrying out feedback-control to the generation of the output potential for the first buffer circuit on the basis of an output potential on a reference side of this current mirror amplifier.

In a level shift circuit, for example, when an input signal IN changes from the L level to the H level, an N-type signal input transistor is made conducting and current flows in the N-type transistor. Accordingly, a first current mirror circuit amplifies the current flowing in the N-type transistor by predetermined number of times, increases the current driving capability for an inverted output node, and changes the inverted output node quickly to the L level. With the change to the L level of the inverted output node, an output node changes to the H level, a P-type transistor (first current interrupting circuit) is made non-conducting by the change, and the current fed from the first current mirror circuit is interrupted. Therefore, even when the power source voltage for the input signal and the inverted input signal is lowered, the operation is performed at high speed.
